Choosing Between MgO Board and Drywall for Modern Projects

09 Feb Choosing Between MgO Board and Drywall for Modern Projects

If you want the best results for new projects, you should pick mgo board. This material is special because it gives better fire safety, keeps out water, and lasts longer. You get something that will not burn, will not bend, and stays strong even in hard places. The most important things to think about are:

• Fire resistance

• Moisture resistance

• Durability

• Installation costs

• Environmental impact

Each of these points can help you choose what works best for you.

Key Takeaways

• MgO board is much better at stopping fire. It can last up to 4 hours in a fire. This makes it safer than drywall.

• Moisture resistance is very important. MgO board only takes in 0.34% water. Drywall can take in much more water. This can cause mold to grow.

• Pick MgO board if you want something strong. It can handle hits and tough weather better than drywall. This means you will spend less on repairs over time.

• Think about the environment too. MgO board is better for the earth. It uses less energy and makes less pollution when made.

• MgO board costs more at first. But it is worth it in the long run. It keeps you safer and lasts longer.

MgO Board vs Drywall Overview

MgO board and drywall are not the same. Both are used for walls and ceilings. They do their jobs in different ways. You should learn about each one before you pick.

What Is Magnesium Oxide Board?

MgO board is made from magnesium oxide, magnesium sulfate, and other natural things. Fiberglass mesh is added to make it stronger. This board can handle fire, water, and hits. It is good for places that need more safety or strength. MgO board does not burn or soak up water. It stays strong in wet or hot spots. It also does not put bad chemicals in the air.

What Is Drywall?

Drywall is also called gypsum board. It is made from gypsum pressed between two paper sheets. Most homes and offices use drywall. It is simple to cut and put up. Drywall is best for rooms that stay dry. It does not do well with water or fire. If drywall gets wet, it can break or grow mold. Drywall can also burn if it gets too hot.

When you look at MgO board and drywall, you see they work differently. The table below shows some main features:

You can see that MgO board is stronger and safer. The chart below shows that MgO board has better impact resistance, bending strength, and fire resistance.

Think about where you want to use the board. MgO board is best for places that need more protection. Drywall is fine for rooms that do not get wet or hot. The best choice depends on what you need. Knowing the differences helps you pick the right one.

Head-to-Head Comparison: Performance

MgO board and drywall do not work the same. They are very different in fire safety, moisture resistance, and strength. This comparison helps you see which one is better for your project.

Fire Resistance

Fire safety is very important when picking a board. MgO board is much safer in a fire than drywall. MgO board can take heat up to 750°C and will not burn. It can last up to 4 hours in a fire. This gives you more time to get out and keeps your building safer. Drywall gets weak after only 20-30 minutes at 400°C. It cannot protect you as long if there is a fire.

Here is a table that shows how each board handles fire:

MgO board also keeps the air cleaner during a fire. It does not make much smoke or let out bad fumes. This makes it safer for people to escape. Drywall can make smoke and harmful gases. This can make it harder to get out safely. Fire safety is a big part of performance, and MgO board is better here.

Moisture Resistance

Moisture resistance is another big difference. Drywall can soak up water and break if it gets wet. Gypsum boards can take in up to 3% water. When wet, they may drip water and even grow mold. This makes the board weak and can cause health problems.

MgO board only takes in 0.34% water. In tests, MgO board stayed dry after 24 hours. It stays strong even in damp places. The table below shows how each board deals with water:

You can use MgO board in bathrooms, kitchens, and basements. It does not lose strength or break down. Moisture resistance is important, and MgO board is the winner.

Durability and Strength

Durability and strength help your walls last longer. MgO board is much stronger than drywall. It can take hits and heavy things without breaking. Even after high heat, MgO board keeps its strength above 5KJ/m². This means it does not get weak in tough spots or fires.

Here is a table that shows how strong each board is:

MgO board can handle bumps and heavy use. Drywall can tear, dent, or crack more easily. This makes MgO board better for places that need strong walls.

Tip: If you want walls that last and need less fixing, pick MgO board for better strength and durability.

In this comparison, MgO board is better than drywall in fire safety, moisture resistance, and strength. You get safer, stronger, and longer-lasting walls. This is why MgO board is the best choice for modern projects where you need good performance.

Environmental Impact

Sustainability

It is good to pick materials that help the earth. MgO board is better for the planet because it uses less energy. Making MgO board needs only about half the energy of drywall. MgO board also takes CO2 out of the air during curing. For every ton made, it removes 0.5 tons of CO2. Magnesium oxide gives off 340 kg of CO2 per ton. Gypsum gives off 740 kg for each ton. MgO boards come from natural places or seawater. This means you do not need heavy mining. MgO board is a smart choice for green buildings.

• MgO board uses less energy to make.

• The process takes CO2 out of the air.

• Raw materials come from cleaner places.

VOCs & Air Quality

Clean air inside is important for your health. MgO board does not let out bad gases or toxins. It stops mold and mildew, so your air stays clean. Drywall can let out chemicals and may grow mold if it gets wet. This can make people sick, especially those with allergies.

Note: Hospitals and schools use MgO board for cleaner air.

Recyclability

You might wonder what happens to old boards. MgO board is easy to recycle and reuse. You can make new things from it. Drywall is harder to recycle and often becomes trash. About 30% of drywall gets wasted when recycling because it is dirty.

Picking MgO board helps the earth and keeps people healthy.

Cost & Installation

Upfront Cost

When you look at the cost comparison between MgO board and drywall, you will notice a big difference. Drywall is cheaper to buy. The price for drywall ranges from $0.40 to $0.50 per square foot. If you add labor, the total cost goes up to $1.50 to $4.00 per square foot. MgO board costs more. You will pay between $1.50 and $3.00 per square foot, with some brands costing $0.93 to $2.16. On average, MgO board costs $2.10 to $2.50 per square foot.

You will also see higher installation costs for MgO board. This is because it is heavier and needs special tools. Drywall is easier and faster to install, so labor costs less.

Long-Term Value

You might pay more for MgO board at first, but it can be more cost-effective over time. MgO board has long-term durability. It resists fire, water, mold, and pests. This means you will spend less on repairs. Over 20 years, the maintenance cost for MgO board stays low. Drywall needs more repairs because it can get damaged by water and mold. This makes the long-term cost higher for drywall.

MgO board lasts longer. It handles more impact and stress. You will not need to replace it as often. This long-term durability makes it a smart choice for busy areas.

Installation Ease

Installing drywall is simple. It is light and easy to cut. Most workers know how to put it up. MgO board takes more work. You must cut it exactly, use special screws, and leave small gaps for expansion. You also need to install the boards evenly. Some brands may be harder to work with.

Tip: If you want a smooth and fast job, drywall is easier. If you want long-term durability, MgO board is worth the extra effort.

MgO board can be faster to install in some cases. It makes less dust and keeps edges clean. Still, the process needs more skill and care.
